Top Forums Shell Programming and Scripting Control cursor position also at bottom of window Post 303043691 by Ralph on Tuesday 4th of February 2020 06:35:01 AM

For some reason LINES is not set in a non-interactive shell - even if checkwinsize is on. (I'm using Bash 5.0 but noticed that back in Bash 4.4, Kali Linux (which is Debian 9) and Raspian, too:
Code:
$ echo $LINES
24
$ bash
$ echo $LINES
24
$ cat showLINES
#!/bin/bash

echo LINES=$LINES

$ shopt checkwinsize
checkwinsize       on
$ bash showLINES
LINES=
 $

Hence I use LINES=$(tput lines) in my script.


But this works:
Code:
$ . ./showLINES
LINES=24
$

GLOBUS-JOB-GET-OU(1)						  GRAM5 Commands					      GLOBUS-JOB-GET-OU(1)

NAME
globus-job-get-output - Retrieve the output and error streams from a GRAM job SYNOPSIS
globus-job-get-output [-r RESOURCE | -resource RESOURCE] [-out | -err] [-t LINES | -tail LINES] [-follow LINES | -f LINES] JOBID globus-job-get-output [-help] [-usage] [-version] [-versions] DESCRIPTION
The globus-job-get-output program retrieves the output and error streams of the job named by JOBID. By default, globus-job-get-output will retrieve all output and error data from the job and display them to its own output and error streams. Other behavior can be controlled by using command-line options. The data retrieval is implemented by submitting another job which simply displays the contents of the first job's output and error streams. By default this retrieval job is submitted to the default GRAM resource running on the same host as the job. This behavior can be controlled by specifying a particular resource manager contact string as the RESOURCE parameter to the -r or -resource option. OPTIONS
The full set of options to globus-job-get-output are: -help, -usage Display a help message to standard error and exit. -version Display the software version of the globus-job-get-output program to standard output. -version Display the software version of the globus-job-get-output program including DiRT information to standard output. -resource RESOURCE, -r RESOURCE Submit the retrieval job to the resource named by RESOURCE instead of the default GRAM service on the same host as the job contact. -out Retrieve only the standard output stream of the job. The default is to retrieve both standard output and standard error. -err Retrieve only the standard error stream of the job. The default is to retrieve both standard output and standard error. -tail LINES, -t LINES Print only the last LINES count lines of output from the data streams being retrieved. By default, the entire output and error file data is retrieved. This option can not be used along with the -f or -follow options. -follow LINES, -f LINES Print the last LINES count lines of output from the data streams being retrieved and then wait until canceled, printing any subsequent job output that occurs. By default, the entire output and error file data is retrieved. This option can not be used along with the -t or -tail options. ENVIRONMENT
If the following variables affect the execution of globus-job-get-output. X509_USER_PROXY Path to proxy credential. X509_CERT_DIR Path to trusted certificate directory. University of Chicago 03/18/2010 GLOBUS-JOB-GET-OU(1)
